VVENTILATOR.

Specification of Letters Patent.

Patented me 4, 1907.

Application filed December 29, 1904. Serial No. 238.701.

T aZZ whom it ntcty concern.-

Be it known that I, JosEPn A. HIOKEY, a citizen of the United States,residing at Philadelphia, in the county of Philadelphia and State ofPennsylvania, have invented certain new and useful Improvements inVentilators, of which the following is a specification.

This invention relates to ventilators, my object being to provide inthis connection-Ya simple, inexpensive and efficient construction andorganization of parts.

IVith this object in view the invention consists in the novelconstructionand combination of parts which will be hereinafter fullydescribed and claimed.

In the drawings :Figure 1 is a perspective view of the lower portion ofa window having my improved ventilator applied thereto. Fig. 2 is asectional view, as on the line 22 of Fig. 1. Fig. 3 is a perspectiveview of the drum for regulating the air. Fig. 4 is a vertical sectionthrough one end of the ventilator, as on the line 44 of Fig. 2.

1 designates a portion of a window frame and 3 the sash therefor. Thesash is fitted to lateral guideways 5 in the frame 1 whereby the sash 3may be raised and lowered, as is well known.

My invention in its preferred embodiment is of the followingconstruction 6 designates a casing comprising the inner and outervertical walls 7 and 8, respectively, the upper and lower walls 9 and10, respectively, and the end walls 11. This casing 6 is adapted to beplaced between the bottom of the window sash and the win-- dow frame andto rest upon a horizontal bar 12 of the frame, the bar 12 being locatedinwardly of the sash. The upper wall 9 is provided with an inset angularportion 13 adapted to receive a corner of the sash 3, and the lower wallis provided with an inset angular portion 14 adapted to receive a cornerof the rail 12. Thus it will be seen that the casing 6 extends into theroom to be ventilated and also into the space between the bottom of thesash and the window frame, and that when the casing is placed in theposition shown, it is maintained therein by the engagement of thecorners of the sash 3 and rail 12 with the inset portions 13 and 14,respectively.

Slidingly fitted to the ends of the casing 6 to conform to the crosssection thereof, are telescopic end extension members 15 which may bemoved toward and from each other to adjust the length of the ventilatorto properly fit the width of the window. These extension members 15 areprovided with other extension members or projections 16 which areadapted to enter the vertical guideways 5 and, taking against the sidewalls thereof, still further assist in holding the ventilator in place.

The outer vertical wall 8 of the casing is provided with a series ofinlet openings 17 to admit air to the casing, and upper wall 9 isprovided with a substantially horizontally arranged, elongated outletopening 18 through which the air passes into the room to be ventilated.

Extending longitudinally through the upper portion of the casing 6 andjournaled in the end walls 11 thereof is a partially rotatable drum 19directly below the opening 18, the upper wall 9 of the casing beingcurved to fit the drum. The drum 19 is provided with a series of largeopenings 20 extending over a portion of its surface, a series ofperforations 21 extending over another portion of its surface and aplain portion 22 having no openings therein. The openings 20 are adaptedto permit the air to pass from the casing 6 to the interior of the drum19, and the perforations 21, when brought into register with the opening18 are adapted to permit the air to pass from the drum into the room tobe ventilated. The drum 19 is provided with a suitable handle or knob 23as a means whereby the drum may be adjusted to bring any number of theperforations 21 into register with the opening 18 and thereby regulatethe admission of air to the room, or to bring the plain portion 22 ofthe drum into register with the opening 18 and thereby close theventilator, or permit no air to pass into the room.

' The lower wall 10 or bottom of thecasing 6 is provided with openings24 to permit any water that may enter the casing 6 to drain out. v

While I have herein shown and described my invention in a desirable andpracticable form yet I do not limit myself to this particularconstruction as the same may be modified without departing from theinvention.

I claim 1. In a device of the class described, the combination with acasing having vertical inner and outer walls, the latter having an inletfor the air, said casing also having its upper portion open for thedischarge of the LOO ITO

air, and provided in said upper portion with an inset'angular portionadapted to receive a corner of a sash, the lower wall of the casingbeing also provided with an inset angular portion to receive a portionof the window frame, said inset portions serving to maintain the casingin position, of a drum journaled in the upper portion of said casing,said drum having a series of perforations adjacent to the dischargeopening of the casing to be moved into and out of register with saidopening, whereby the discharge of the air from the casing is regulated,said drum being also provided at a point substantially opposite to saidperforations with an opening for the passage of the air into said drum,and having an imperforate portion midway the perforations and saidopening.

2. In a device of the olass described, the combination with acasinghaving vertical inner and outer walls, the latter having an inlet forthe air, said casing also having its upper portion open for thedischarge of the air, and provided in said upper portion with an insetangular portion adapted to receive a corner of a sash, the lower wall ofthe casing being also provided with I an inset angular portion toreceive a portion of the window frame, said inset portions serving tomaintain the casing in position, of a drum j ournaled in the upperportion of said casing, said drum having a series of perforationsadjacent to the discharge opening of the casing to be moved into and outof register with said opening, whereby the discharge of the air from thecasing is regulated, said drum being also provided at a pointsubstantially opposite to said perforations with an opening for thepassage of the air into said drum, and having an imperforate portionmidway the perforations and said opening, and an extension membertelescopically mounted upon the end of said casing for adapting theventilator to windows of varying widths.

In testimony whereof I afiix my signature I in presence of twowitnesses.
